C2 Communications

What C2 Communications does

C2 Communications is an Australian privately held telecommunications company headquartered in Hawthorn, Victoria, that delivers cloud-based voice, unified communications, and business-grade internet services to small, mid-market, and enterprise customers across all six Australian states. The company operates as Australia's first and longest-standing 3CX Titanium Partner (since 2008/2019) and as a Microsoft certified Operator Connect provider (since 2021), positioning its portfolio around two flagship voice platforms — 3CX Phone System and Microsoft Teams Calling — complemented by Tier 1 SIP Trunking, Inbound Business Numbers (13/1300/1800), Business NBN, NBN Enterprise Ethernet, and Fibre-Optic Internet services with symmetric speeds up to 10 Gbps.

The core technology stack centres on 3CX hosted on AWS infrastructure for cloud deployments, with on-premise options available, and integrates with Microsoft Teams via Operator Connect over a managed Azure-peered network. SIP services are delivered through Tier 1 direct routing with quality of service guarantees, and the system supports CRM integrations (Salesforce, HubSpot, Microsoft Dynamics, Zoho) and Microsoft 365 SSO. AI features include an AI Receptionist for intent-based call routing and lead qualification, voicemail-to-text transcription, real-time call transcription, and predictive analytics for staffing optimization. The company employs 11–50 staff and serves 500+ customers nationwide, generating revenue primarily through recurring monthly subscriptions priced from $10/user/month for Microsoft Teams Calling up to $2,199/month for 10 Gbps fibre, with multi-year contracts available on enterprise connectivity tiers and no lock-in on most voice plans.

The business is founder-led by Craig Macdonald and operates without disclosed external investment, alongside a sister company IT For Business (launched 2007) that provides complementary managed IT services and serves as a referral channel for integrated IT-and-voice deals. Distribution combines direct sales (website, phone 1300 699 130, email), a SIP and 3CX reseller program, and the Microsoft partner channel, with go-to-market supported by SEO-optimized city landing pages, educational content marketing, and case studies across healthcare, legal, education, automotive, real estate, transportation, and not-for-profit verticals.
